Application filedOctober 11, 1922. Serial No. 593,935.

To all whom it may concern:

Be it known that WILLIAM CHARLES RAN- KIN, acitizen of the British'Empire, resid ing at Main Street, Frankton Junction,town

ment Windows and such like, of which the following is a specification,

for hinged articles comprising amovable member hinged to a fined member such as a casement window hinged to a frame. It is hereinafter described in its application to a casement window. The object of the in-, vention is to provide a device adapted to hold in any desired position a casement window with a maximum opening approximating 90 degrees, which opening is much wider than is now possible with the present style of casement stay. By my invention also a window may be locked in a slightly open position to admit of the circulation of air and yet so as to be burglar proof. By my invention also very little space is taken up when the window is closed. The stay as now used which is dropped and placed over a pin is easily accidentally knocked off the pin and is liable toswing and break the window or allows the window to bang open or shut and my invention obviates this clefect. The invention consists in the features, combinations and arrangements of parts secured and operating as herein described and more particularly pointed out in the claim.

In the accompanying drawings illustrating the invention Figure 1 is a view showing the device in position where the casement window is closed. Figure 2 is a View showing the device in position when the easement. is locked open to its widest extent; Figure 3 is a front elevation of-the device. Figure 4 is a plan of the device. Referring to these drawings a bracket or plate (1) is provided with two lugs 7, 7 and with holes 10 to take fastening'screws. A rivet pin 7 is secured to and between the lugs 7, 7 and forms the axis pin for one end 2 of a movable curved arm 2 said end 2 being drilled to take the pin 7 The end 2 of the arm 2 fits and works between the lugs 7, 7 The arm 2 is drilled at intervals with holes 9, 9. adapted to take a locking This invention relates to fasteners or stays 4) do not run parallelto either side ofthe arm 2 nor are they all central of the arm 2' the arm 2 not being in the same work-ing are as that described by the plates or brackets l, 3to which it is attached, fThe tapered locking pin 4 has aring topend 4 forlift ingpurposes. Another plate or bracket 3- has three lugs 8, 8 8 one of which (8) is at the edge of the plate 3, theother two 8 8 act as guides for the arm 12 between,

plate 3 between lugs 8 and 8 through which the arm 2 is adapted to slide. A hole 12 is drilled through each of these three lugs at one side thereof and is tapered to take the tapered locking pin 4. A spring 5 surrounds the locking pin 4 and is held between lug 8 and pin 6 which passes through the locking pin. the tapered pin 4 is kept normally home in the tapered hole 12. 1

Another set of holes 12 is drilled through the three lugs. near the other side thereof from the other set of holes 12 so that by changing the locking pin 4 from one set of holes 12 to the other 12 andturning the device upside down it is made attachthem, There is a rectangular slot 22 in the By this spring able to either a left or a right hand swung on both sides of the arm for use in the ordinary and the reversed position of the device. Three of these holes 9 are by preference placed close together so as to afford a small variation of position for the locking pin 4 for locking the window when closed. v Q

In operation a hole 23 of suitable size is bored through the fixed member such aswhen the device is used on a window 20, through the fixed j amb 15 in a suitable position, The second plate 3 is then secured to the jamb 15 with its bottom edge resting near the sill 16 as shown in Figures 1 and 2 and with the slot 22 over the hole 23 and corresponding therewith and this plate 3 is so situated that the curved arm 2 will pass through the rectangular slot 22 in it and into the hole 23 bored as above mentioned in the jamb 15. The arm 2 is then passed. between lugs 8" and 8 through slot 22 and into hole 23, then the plate 1 is secured to the hinged member in this case, the bottom rail 14- of the window 20 and when the windowQO is qiii teclosed the end of th'e ar m 2 has moved out of sight behind the amb 15 through the hole 23 in it. The locking pinljis then inserted in one of the holes 9 spring around'it, any hole in the arm as desired. I

A'fastener for casement Windows and the like comprising in combination a window frame, a horizontal swinging sash mounted f on the frame, a bracket secured to the sash,

a curved arm having one end pivoted to the bracket vand provided with a series of openings, .one side of the sash being provided with a slot for accommodating the inner portion of the arm when the sash is in a closed position, another bracket provided with a slot and secured to the frame in alignment with the slot therein so that the arm may slide therethrough, a plurality of suitably spaced lugs extending from the last mentioned bracket and provided with pairs of aligning openings and a spring controlled fingeroperated pin for engagement with either set. of aligning apertures in the lugs of the second mentioned bracket and adapted for engagement with the openings in the arm and the openings in the arm being arranged out of parallelism with the sides thereof.

In testimony whereof he has aflixed his signature in presence of two witnesses.
